Here is my attempt of a DIY Peristaltic Fert pump set-up.
Thanks to everyone here who has a similar set-up, I have got alot of helpful tips from your posts.
Having fun so far setting up the dosing schedule, already had my first (since DIY dosing) of a green tank , fixed now. So back to testing much much smaller doses (although I didn't dose anymore than I usually do by hand).
Having fun getting it right, anyone thinking of doing a similar set-up, go ahead and do it.
